Title: Method of winding yarn
Inventor: SHIMADA KOJI
IPC: B65H54/38
Filed: 1985-04-26
Abstract: PURPOSE:To obtain a good form of winding having a uniform surface hardness without ruggedness on the surface of yarn by continuously varying an angle between an entering passage of yarn to a winding bobbin in a position released from a traverse guide means, and the axis of said bobbin, during winding. CONSTITUTION:During the operation of a cylinder 13, i.e., while yarn removing guides 16a, 16b are placed in the position of 16', when a traverse width restricting guide 3 is in the position of 3a, the traverse width restricting guide 3a does not interfere with a yarn Y, which is wound at a normal swinging width. When the guide 3a comes to the position of 3b by means of a driving motor, however, the guide 3 interferes with the yarn Y being traversed. Thereby, when the guide 3 is headed for the winding center, the angle theta between the line of the yarn Y connecting the swinging width restricting point X to the winding pint Z and the winding bobbin, varies to be smaller, while it varies to be larger when the guide 3 is headed for both ends. Accordingly, by utilizing variation in the speed of the yarn Y due to the size of the angle theta, the position of yarn pool can be controlled without centralizing it, to make the surface hardness of a package uniform and improve the form of winding.

Abstract: PURPOSE:To prevent the generation of segregation in the molten metal in a reflection furnace by providing an inductor to the bottom of the reflection furnace to stir the molten metal by the moving magnetic field thereof at the time of gradually inclining the reflection furnace and tapping the molten metal at every specified rate. CONSTITUTION:While the molten metal 2 in the cylindrical reflection furnace 1 is heat-insulated by a burner 3, the molten metal level is detected by a molten metal level sensor 11 and a command is emitted by a controller 10 to a cylinder 8 to extend a piston 8a to a specified length so that the molten metal 2 is tapped at every specified rate per unit time from a tap hole 4a. The inductor 12 is provided to the bottom of the reflection furnace 1 of such molten metal supplying device and the molten metal 2 is stirred by the interaction of the moving magnetic field of the inductor and the eddy current in the molten metal 2 generated by the same. The angle of inclination of the reflection furnace 1 is detected by an angle detector 14 and the inductor is controlled by an inductor driving circuit 13 in such a manner that the moving magnetic field weakes as the molten metal 2 in the reflection furnace 1 decreases with an increase in the angle of inclination. The generation of the segregation in the molten metal 2 in the reflection furnace 1 is thereby prevented and the oxidation and waving of the molten metal 2 are prevented.

Abstract: PURPOSE:To eliminate an influence of a flicker even when a light source is turned off by the commercial electric power source by permitting the register part of an image sensor to operate as an analog memory under the on-off control of a clock signal. CONSTITUTION:A signal photoelectrically converted by photodetection part 3 of the image sensor is transferred to register part 1 when transfer pulse SH is input to transfer gate 2 with a timing pulse. Once pulse SH is output to gate 2, clock signals phi1-phi4 stop and the transferred signal is stored in register part 1 until the next clock signals phi1-phi4 are output. When clock signals phi1-phi4 are output with the next timing pulse, the stored data of register part 1 are output as video output successively with clock signals phi1-phi4. Consequently, no influence of a flicker is exercised even when the light source is turned on by the commercial electric power source.

Title: Vitrifide grinding element
Inventor: NAGATA AKIRA
IPC: B24D3/14
Filed: 1986-04-21
Abstract: PURPOSE:To maintain pores with any desired porosity by giving an inorganic hollow substance functioning a pour forming agent, a softening point which is higher than the specific baking temperature for vitrifide bond, and thereby suppressing the dimension shrinkage at the time of baking to possible minimum. CONSTITUTION:Super-abrasive grains 1 are used for this grinding wheel, including inorganic hollow substance 4. The porosity of vitrifide grinding wheel can be adjusted easily by changing the content of this hollow substance 4. Further, this substance 4 will remain in the grinder element even at the time of baking, which will minimize possible drop of the abrasive grain retention force, or drop of the strength of grinding wheel. Because of having a softening point higher than the specific baking temperature of the vitrifide bond 2 for super- abrasive grains, this hollow substance 4 will not soften even at the time of baking, which should suppress eventual shrinkage in baking to the minimum. Thus the construction of a grinding wheel can be maintained as desired, and products management will be facilitated.

Filed: 1993-03-12
Abstract: PURPOSE:To stably manufacture a foaming type light-weight aggregate containing fly ash as a main material by forming a protrusion in a combustion zone of at least a specific temperature range of a rotary kiln. CONSTITUTION:A protrusion 2 is formed in a combustion zone A of at least 800-1000 deg.C of a rotary kiln 1. When a material pellet is supplied from a supply port 3, the pellet is heated and burned according to a temperature curve shown by a broken line by heating from a burner 4. The pellet is abruptly increased in strength when exceeding 800 deg.C. A pellet filling layer is raised by the protrusion 2 to improve contact with oxygen in combustion gas, thereby burning to remove unburned carbon in the pellet. Fly ash is sufficiently foamed without decreasing reducing reaction of Fe2O3 at a softening temperature of the ash, i.e., at the time of foaming and reducing in weight the pellet in a next burning zone B of 1000 deg.C or higher, thereby manufacturing a stable light-weight aggregate.
